What could be a consequence of over greasing bearings?

Over greasing bearings can lead to high friction in the bearing chamber, which is an important consideration in the maintenance of mechanical systems. When too much grease is applied, it can create excessive pressure within the bearing, affecting the internal clearance and potentially leading to increased operating temperatures. This high pressure can also impede the bearings' motion, causing them to work harder, which naturally increases friction.

Proper lubrication is crucial for reducing friction and wear; it allows the bearings to turn smoothly while minimizing metal-to-metal contact. However, when the bearing is overfilled with grease, it can lead to pack-off situations where the grease becomes trapped and is unable to evenly distribute, resulting in higher friction levels than what is desirable. Thus, ensuring the right amount of grease is critical for optimal bearing performance and longevity.
